Description

  The present invention relates to a method for controlling incoming call notification means of a mobile phone device, and more particularly to a mobile phone device that automatically switches incoming call notification means depending on the possession state of the mobile phone device.

  In recent years, mobile phones are owned by everyone and are used everywhere. In general, when a mobile phone device receives an incoming call, the built-in speaker rings at a high volume to notify the user of an incoming call notification.

  For example, when the user is on a train or is in a meeting. As a means for preventing such trouble due to noise, notification of incoming calls by a vibrator set in a manner mode is known. However, since the above function is a manual setting, there are problems such as forgetting to set.

  In response to the above problems, the mobile phone device is equipped with a temperature sensor, and if the temperature exceeds the intermediate temperature between the human body contact temperature and the ambient temperature, it is determined that the person is carrying it and the incoming call notification means is automatically switched. Proposals have been made (see, for example, Patent Document 1).

  However, the determination of the possession status by the temperature sensor cannot always determine that the person is possessing such as when the mobile phone device is put in clothes.

  In addition, in a mobile phone device in which a receiver that reproduces a call tone and a speaker that reproduces a ring tone are composed of a single sounding body, the ring tone that emits a large volume causes a problem with the ear drum. 1) Gradually increase the ring volume. 2) Regulate the volume so as not to damage the eardrum. 3) Limiting the rate of increase in volume that exceeds the reference sound. (See, for example, Patent Document 2 and Patent Document 3).

  However, each proposal has the following problems. 1) Gradually increase the ring volume. 2) Regulate the volume so as not to damage the eardrum. If the user puts the mobile phone device in a bag or pocket of clothes, the user will not be able to get enough volume to recognize that the ringtone is ringing, or the volume will be enough There is a problem that it takes some time until.

3) Limiting the increase speed of the volume exceeding the reference sound. There is a problem that the ring melody created by content providers and users who distribute ring melody cannot be faithfully reproduced.

Control program data microprocessor 160, microprocessor 160 executes, and a memory 161 in which data is stored, such as the operation result.

  In addition, the cellular phone device 100 receives a call voice decoder 111 that decodes received voice data and converts it into a received voice signal, a call voice encoder 120 that encodes a transmitted voice signal and converts it into transmitted voice data, and an instruction from a microprocessor 160. A ring tone sound source 110 that generates and outputs a sound and a ring tone melody, a digital filter 112 that performs a pass band limiting process in each reproduction band on the ring tone signal or the received voice signal from the ring tone sound source 110 or the call voice decoder 111; A D / A converter 113 that converts a ringtone signal or a received voice signal into an analog signal, a volume setting unit 114 that sets the ringtone signal or the received voice signal to a predetermined volume, an amplifier that amplifies the ringtone signal or the received voice signal, and a speaker A speaker amplifier 115 for driving 116; It has the raw to the speaker 116.

  Furthermore, the cellular phone device 100 includes a microphone 123 that converts a transmission voice into an electrical signal, a microphone amplifier 122 that amplifies a transmission voice signal from the microphone 123, and an A / D converter that converts the transmission voice signal into a digital signal. 121, a pulse sensor 172 disposed on the side surface of the operation unit 170, a pulse sensor 171 disposed on the same surface as the speaker 116 and in the vicinity of the speaker 116, and an incoming call for notifying a user of the mobile phone device 100 by light. The LED 180 includes a vibrator 181 for notifying a user of the mobile phone device 100 by vibration, and an operation unit 170 for sending predetermined operation information to the microprocessor 160 by key input.

  In the standby reception state, the cellular phone device 100 performs an intermittent reception operation as shown in FIG. 5 in order to receive an incoming signal from the base station. The reception period in the intermittent reception operation is several hundred milliseconds to several seconds. Further, in the intermittent reception operation, the microprocessor 160 operates the duplexer 102, the reception circuit 103, and the demodulator 104 only in the reception section 414 to receive reception control information, and receives desired information such as incoming information, and also receives the reception operation. Control is performed so that the consumed current consumed by the is reduced.

  The pulse sensors 171 and 172 are photoelectric pulse wave sensors, which detect infrared light reflected from the LED inside the human body with a photodetector, detect a change in blood flow through the blood vessel, and output it as a pulse wave signal. The pulse wave signals output from the pulse sensors 171 and 172 are quantized by the AD converters 173 and 174 and read by the microprocessor 160 as pulse wave data.

  The volume setting unit 114 has a circuit configuration in which an arbitrary volume can be set according to a command from the microprocessor 160, and can also be set to a mute state according to a command from the microprocessor 160. The vibrator 181 has a circuit configuration that generates vibration by driving a motor (not shown) according to a command from the microprocessor 160. The incoming LED 180 has a circuit configuration in which the LED blinks periodically according to a command from the microprocessor 160.

  Next, the operation of the mobile phone device 100 according to the embodiment of the present invention will be described. The average human pulse rate is 70-80 per minute in a resting state in adults. Therefore, in order to detect the period of the pulse wave, it is necessary to sense the pulse sensor for at least one second. When the pulse sensor is constantly sensing, the current consumption increases remarkably and the standby time is shortened. On the other hand, when the pulse sensor is sensed at the time of an incoming call, a delay of 1 second or more occurs in the time for ringing a ringtone from the incoming call.

  In the mobile phone device 100 according to the embodiment of the present invention, a change in pulse wave is detected in the reception state during the intermittent reception operation in the standby reception state, and the pulse wave cycle is detected only when there is a change. Means for determining a human body contact or a human body possessing state is used. As a result, the current consumption due to sensing by the pulse sensor can be minimized, and the incoming notification means can be selected without delay when an incoming call is received.

  Next, means for determining the human body possession state processed by the microprocessor 160 will be described with reference to the flowchart of FIG. If the cellular phone device 100 performs the intermittent reception operation shown in FIG. 5 and is in the non-reception state 412, it is determined in step S401 that it is non-reception, and the possession state determination process is not performed. Next, in the reception state 413, it is determined in step S402 that reception is in progress, the pulse sensor 172 is sensed, and pulse wave data is read from the A / D converter 174. Next, it is compared with the pulse wave data read in the previous reception state 411 (step S403). If there is no change, the pulse wave data read this time is used for the comparison processing in the next reception state 415 (step S403). Is stored and updated in the memory 161 as pulse wave data in the reception state (step S405), and is determined to be in a non-possible state (step S408). If it is determined that there is a change in the comparison process (step S403), the pulse sensor 172 is sensed for about 1 second and pulse wave data is continuously acquired via the A / D converter 174, and the pulse wave data is periodically changed. Measure (Step S404). Next, it is determined whether or not there is a period change from the measurement data (step S406), and if there is no period change, it is determined that it is not in possession (step S408). If there is a period change in the determination process (step S406), it is determined to be in the possessed state (step S407).

  In addition, the means for sensing the pulse sensor 171 disposed in the vicinity of the speaker 116 to determine contact or non-contact with the ear is the same as the means using the pulse sensor 172 as described above.

  When the user of the cellular phone device 100 holds the pulse sensor 172 as shown in FIG. 3A, the microprocessor 160 determines that the user is in the possessed state using the means for determining the possessed state of the human body. . If there is an incoming call at this time, the microprocessor 160 1) instructs the volume setting unit 114 to mute the incoming call sound and causes the incoming LED 180 to blink. Alternatively, 2) A command to mute the ringtone is given to the volume setting device 114 and the vibrator 181 is driven. Alternatively, 3) The volume setting unit 114 is instructed to set the volume to a volume that does not bother nearby people, and the user is notified that it is in an incoming state.

  In addition, the operations 1), 2), and 3) are selected according to the setting information input in advance from the operation unit 170 by the user of the mobile phone device 100.

  In the state where the user of the cellular phone device 100 is using the pulse sensor 172 in contact with the ear as shown in FIG. 3B, the microprocessor 160 uses the means for determining the human body contact state. It is judged that. If there is an incoming call at this time, the microprocessor 160 4) instructs the sound volume setting unit 114 to mute the incoming call sound and drives the vibrator 181. Alternatively, 5) The volume setting unit 114 is instructed to set the volume to a level that does not impair the ear, and the user is notified that the incoming call is in progress.

  The operations 4) and 5) are selected according to the setting information input from the operation unit 170 in advance by the user of the cellular phone device 100.

  Further, in the mobile phone device 100 according to the embodiment of the present invention, in the reception operation after the incoming call, the pulse sensors 172 and 174 are sensed to detect a periodic pulse wave change and to detect a periodic change of the pulse wave. In this case, the microprocessor 160 autonomously instructs the volume setting unit 114 to mute the ringing tone and drives the vibrator 181. Alternatively, the volume setting unit 114 is limited in volume. Therefore, even if the user of the mobile phone device 100 touches the pulse sensors 172 and 174 after receiving a call, the ringtone can be stopped or the volume of the ringtone can be reduced.

  As described above, according to the embodiment of the present invention, since the pulse wave, which is human body-specific information, is used as the determination means for the possessed state of the human body or the human body contact state, the incoming notification unit is selected. It is possible to reliably determine whether the human body is in possession or the human body contact state.

  INDUSTRIAL APPLICABILITY The present invention has an effect of accurately determining a possessing situation and automatically making an appropriate incoming notification according to the possessing situation, and is useful for a mobile phone device or the like.
